Yes.
I have not inquired into this matter fully, but I can tell you that under the guidelines set by the Supreme Court in the P.E.I. reference, the idea is that the government should implement the recommendations of the committee, unless it gives reasons for not doing so or for doing so partially, and then this decision can be contested. For example, in Quebec courts, decisions of the government not to give effect to wage recommendations have been contested and in some cases have been found to be inconsistent with judicial independence.
So that's the way it works.
